Depends on your overflow and how much flow it can handle. Also depends on the type of fish you want to keep.
the guy i got it from had a pump with 950 gph on it but that sounds like to much for me he had it for saltwater of course
As mentioned already, you should determine what the external overflow can handle - in general I see that as being the "bottle neck" to flow. Also it also will depend of how you plan to plumb and head pressure. The previous owner may have had a pump that's 950gph on paper, but unlikely it was turning water at that exact rate.
Once you've confirmed the overflow question, how much turnover you want, you can look into DC pumps out there. I like it them because you have the flexibility of controlling flow with the controller.

+1 on the DC pumps. They don't waste electricity, are quiet, and adjustable. HOWEVER....I just had my Deepwater Aquatics DC pump ballast die on me. Thankfully, I have backups. But just be careful...get a backup pump if you can.
